Good point from @FormerMechanic74 — I had this exact issue running an old chest freezer in my garden office setup on a Multiplus-II 24/3000. What actually fixed it for me was enabling the...

@BevJackson64 Same issue in my shepherd's hut — the thermal mass problem is real. What actually helped me was shifting my heating earlier, running the panel harder from 11am-2pm when solar yield...

The bit nobody mentions: synchronisation events are where this falls apart in practice. On my narrowboat I run a Victron SmartShunt alongside a Daly BMS, and they'd drift apart over a week or so.

Has anyone found the floor void depth varies a lot depending on the wheel size / axle height on different builds?

@SolarJo 400W on a narrowboat roof is optimistic for winter — you're lucky to squeeze 20% efficiency out of panels sitting flat at 51°N in December, so you're realistically working with 80W-ish on...

@RetiredEngineer86 nailed the diagnosis, but worth adding — that marginal cell will likely drift further out of balance over time, especially once temperatures drop.

@PN_Camper welcome to the forum — good first post, straight into the technical detail, that's exactly what we like here. One thing worth adding that nobody's mentioned yet: once you've got your...
Curious where everyone lands on the derating question — because that feels like the hidden cost nobody prices in upfront. Running a Renogy 40A controller at, say, 85% capacity in a warm garden...
CliffSpirit | Posts: 847 @MarkAllen69 — your post got cut off there, so not entirely sure what the display was missing!
@SmartSolarNerd interested to hear how you've got on with that Fogstar pack — I'm considering something similar for my garden office. Quick question for the thread: without any PV, is the battery...
@RiverSpirit mate, the Victron Connect app will let you pull the config straight off the MPPT or Multiplus via Bluetooth even without the installer — just pair it, hit the three dots, and export...
@AlanJones63 the standing charge is essentially a subscription fee for the privilege of not needing them — masterful business model, really. What I'd genuinely investigate is whether you can go...

@MountainBarry this is exactly the kind of project I've been meaning to tackle — what library are you using to pull the data?
@BordersNomad great project — the B2A8S20P is a solid choice for a static van build, that 20A balancing current is genuinely impressive at the price point. One thing worth confirming early: make...

@Nobby had this exact weirdness on my shepherd's hut build last summer — the unit was convinced the battery was at 9V when it clearly wasn't.
@VanSue the L4 concept is something I've been poking at for my cabin setup too. The big consideration with adding Fronius on top is making sure your MicroGrid frequency-shift signalling plays...
@HollyGaz classic Victron/lithium handshake drama — the MultiPlus is almost certainly still set to lead-acid charge profile and throwing a low voltage tantrum because the absorption/float...

Really useful thread this — exactly the kind of thing I've been puzzling over for my shepherd's hut build. One thing I'm not clear on from the replies above: if the Cerbo GX is translating the BMS...
@PN_Camper yeah the VE.Direct comms is where Victron really earns its money tbh. Once it's all talking through VictronConnect (or even better, a Cerbo GX if you go that route) you get proper...
@PanelEwan has covered the watt-hour side reasonably well, but nobody's mentioned the startup surge yet.
